[0002] The function of a food waste disposer is to crush food waste and purify the exhaust gas generated from it, thereby solving the pollution problem caused by food waste. Traditional food waste disposers typically only use activated carbon filtration for simple exhaust gas treatment, resulting in problems such as a single treatment method, poor treatment effect, and high treatment cost.

[0003] To address this issue, Chinese Patent Publication No. CN222970592U discloses a structurally improved food waste disposer. The exhaust gas treatment device of this food waste disposer includes a purification box and a filter. The purification box is used to cool and pre-purify the high-temperature exhaust gas heated by the heating component, and the filter is used to perform secondary purification of the exhaust gas. The combination of the two not only provides a variety of treatment methods but also has a good treatment effect.

[0004] However, the patent still has the following problems: First, the high-temperature exhaust gas is cooled only by the purification box. In order to achieve effective heat exchange, there must be a sufficient amount of purification medium in the purification box. Therefore, the volume of the purification box needs to be large enough, which makes the purification box occupy a large space and has the problem of poor cooling effect. Second, the exhaust gas treatment process requires two purification steps, which is relatively complicated. In addition, the purification medium in the purification box and the filter medium in the filter need to be replaced regularly, which is troublesome to operate and has high purification cost.

Detailed Implementation

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0025] Reference Figures 1 to 4 An improved food waste disposer includes a crushing device and an exhaust gas treatment device. The crushing device comprises a crushing bucket 21, a crushing component 22, and a heating component 23 that cooperate with each other. The crushing bucket 21 is used to hold food waste, the crushing component 22 is used to stir and crush the food waste, and the heating component 23 is used to heat and evaporate the waste liquid in the food waste, thereby forming high-temperature exhaust gas. The exhaust gas treatment device includes a condenser 31 and a purification chamber 32. The condenser 31 is disposed between the crushing bucket 21 and the purification chamber 32 and is used to cool the high-temperature heated exhaust gas. Specifically, the high-temperature exhaust gas is rapidly cooled by the condenser 31 to form liquid water or room-temperature exhaust gas, and then purified by the purification chamber 32, thereby achieving effective treatment of food waste exhaust gas.

[0026] Reference Figures 1 to 5 The purification box 32 includes a detachably connected box body 321 and a cover 322. The box body 321 and the cover 322 are sealed together. The box body 321 contains a purification medium 323. The purification medium is not limited to liquid or solid. Liquid can be water or other substances, and solid can be activated carbon or other substances. In practical applications, the medium can be selected according to the nature of the kitchen waste. No limitation is made here.

[0027] Reference Figures 1 to 5 In this embodiment, the purification medium 323 is preferably water. Experiments show that water, as the purification medium 323, can simultaneously adsorb and degrade organic matter in both the ambient temperature waste gas cooled by the condenser 31 and the liquid water, thus achieving a purification effect. It also has a certain auxiliary cooling effect, ensuring effective treatment of waste gas generated from kitchen waste. After treatment, the liquid water is temporarily stored in the purification tank 32. When the liquid water accumulates to a set amount, when the working time of the purification tank 32 reaches a set time, or when the purification capacity of the purification tank 32 decreases, the water in the purification tank 32 should be replaced promptly to ensure the purification effect. In other embodiments, the purification tank 32 can be divided into sections. For example, the purification tank 32 can have a waste gas treatment chamber and a waste liquid treatment chamber. The cooled ambient temperature waste gas is discharged into the waste gas treatment chamber for purification treatment, and then discharged back into the crushing barrel 21 to participate in the next round of waste gas treatment cycle; the cooled liquid water is discharged into the waste liquid treatment chamber for purification treatment and storage, and is periodically discharged. The purification media in the exhaust gas treatment chamber and the waste liquid treatment chamber can be the same or different, depending on the actual needs.

[0028] Reference Figures 1 to 3 The condenser 31 can be a conventional condenser with small size and good cooling effect in the existing technology, such as a plate condenser or a spiral tube condenser. It can be reasonably selected according to actual needs, and there is no limitation here.

[0029] Reference Figures 3 to 5 The waste gas treatment device also includes a waste gas conveying assembly, which sequentially conveys the waste gas from the crushing bin 21 to the condenser 31 and the purification chamber 32, and then conveys the waste gas from the purification chamber 32 back to the crushing bin 21. The waste gas purified by the purification chamber 32 is then discharged back into the crushing bin 21 for the next round of waste gas treatment cycle. This ensures that the entire waste gas treatment process of the food waste processor achieves internal circulation, preventing external discharge and thus making it more environmentally friendly and enabling thorough treatment of food waste.

[0030] Reference Figures 3 to 5The exhaust gas conveying assembly includes a conveying pipe and a power source. The crushing barrel 21, the condenser 31 and the purification box 32 are connected in a closed loop through the conveying pipe, and the power source is used to guide the flow direction of the conveying pipe. Specifically, the exhaust gas conveying assembly includes a first inlet pipe 33, a second inlet pipe 34, and an outlet pipe 35. The first inlet pipe 33 connects the crushing barrel 21 and the condenser 31, and is used to convey the high-temperature exhaust gas in the crushing barrel 21 to the condenser 31. The second inlet pipe 34 connects the condenser 31 and the purification chamber 32, and is used to convey the room-temperature exhaust gas or the liquid water formed by cooling in the condenser 31 to the purification chamber 32. The end of the second inlet pipe 34 should extend into the purification medium 323 to ensure that the room-temperature exhaust gas can be more fully mixed with the purification medium 323, thereby improving the purification effect. The outlet pipe 35 connects the purification chamber 32 and the crushing barrel 21, and is used to convey the exhaust gas purified by the purification chamber 32 back to the crushing barrel 21. The head of the outlet pipe 35 should be located above the purification medium 323 to ensure that the purified exhaust gas is sent out. To increase gas delivery efficiency and limit the gas flow path, a blower or vacuum pump can be installed on the corresponding pipeline as a power source. As a preferred option, in this embodiment, a vacuum pump 36 is installed on the gas outlet pipe 35 to ensure that the waste gas purified by the purification box 32 can be delivered back to the crushing barrel 21 in a timely manner.

[0031] Reference Figures 1 to 5 The food waste disposer also includes a body 1, which has an installation cavity 11 and a hollow portion 12 communicating with the installation cavity 11. A crushing bucket 21 is installed in the installation cavity 11, and a purification box 32 is detachably installed in the hollow portion 12. Specifically, the side wall of the box 321 is provided with a handle 324 for easy pulling. When it is necessary to replace the purification medium 323 in the purification box 32, the purification box 32 can be removed simply by using the handle 324, making it simpler and more convenient to use.

[0032] Reference Figures 1 to 4 The crushing bin 21 includes an inner bin 211, an outer bin 212, and a bin lid 213. The outer bin 212 is fixed inside the mounting cavity 11, and the inner bin 211 is detachably fitted inside the outer bin 212. A heating element 23 is provided between the inner bin 211 and the outer bin 212. When it is necessary to remove the processed kitchen waste, simply lift the inner bin 211. The bin lid 213 is detachably mounted above the inner bin 211 and the outer bin 212, and the bin lid 213 has an air inlet chamber inside. This air inlet chamber can be interconnected with the inner bin 211, the first air inlet pipe 33, and the air outlet pipe 35 through vent holes, thus enabling the transfer connection between the crushing bin 21 and the waste gas treatment device.

[0033] Reference Figure 3The crushing assembly 22 includes a rotating cutter head 221 and fixed cutter heads 222. The rotating cutter head 221 is rotatably disposed at the bottom center of the inner barrel 211, and several fixed cutter heads 222 are fixed to the bottom side wall of the inner barrel 211. Since kitchen waste contains hard ingredients such as bones and food scraps that are difficult to process, the cooperation between the rotating cutter head 221 and the fixed cutter heads 222 ensures that all kitchen waste is ground and pulverized. Specifically, the inner barrel 211 is provided with an upper clutch 223 connected to the rotating cutter head 221, and the outer barrel 212 is provided with a lower clutch 224. The mounting cavity 11 is provided with a drive motor 225 connected to the lower clutch 224. Therefore, when the inner barrel 211 is placed inside the outer barrel 212, the upper clutch 223 and the lower clutch 224 can engage with each other, thereby achieving quick installation.

[0034] Reference Figures 1 to 5 The working principle of this utility model will be analyzed in detail below: Step S1: The kitchen waste in the crushing bin 21 is crushed and heated to form high-temperature exhaust gas. In this step, the crushing component 22 and the heating component 23 in the crushing bin 21 work simultaneously to crush the kitchen waste and heat and evaporate the waste liquid generated by crushing to form high-temperature exhaust gas with a certain pressure.

[0035] Step S2: The high-temperature exhaust gas is condensed to form liquid water. In this step, a condenser 31 is used to condense the high-temperature exhaust gas. The high-temperature exhaust gas enters the condenser 31 through the first inlet pipe 33. Part of it is rapidly cooled to form liquid water, and the other part is cooled to form room temperature exhaust gas.

[0036] Step S3: Collect liquid water into purification tank 32 and discharge it periodically. Ventilation-temperature exhaust gas is discharged into purification tank 32 for purification treatment and then returned to crushing drum 21 for inclusion in the next processing cycle. In this step, liquid water and ventilation-temperature exhaust gas are discharged together into purification tank 32 through the second inlet pipe 34. The liquid water is treated by purification medium 323 and stored in purification tank 32. After treatment by purification medium 323, the residual exhaust gas is transported back to crushing drum 21 through outlet pipe 35 by the suction pump 36, thus being included in the next processing cycle, thereby achieving closed-loop internal circulation treatment.

[0037] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
